Clipture 1.5.2: In-Place Replay Saving & Zero-Copy MP4 Persistence

[1.5.2] - 2026-09-10

In-Place Replay Saving & Zero-Copy MP4 Persistence

• In-Place Replay Persistence & Zero-Copy Finalization: Replaces disk/memory duplicate muxing with a dedicated packet arena (replay/InPlacePacketArchive). Video and normalized AAC audio samples are written directly into private .clipture-replay/*.recording arenas inside the user's save folder, finalizing in place via atomic MP4 atom construction (ftyp/free/64-bit mdat/moov) with zero media reads or writes during save.
• Rolling Disk Arena & Bounded Storage: Implements packet lease protection and hard arena caps, reusing retired unleased slots and zeroing free blocks upon detachment to keep disk usage strictly bounded.
• Consume-on-Save Window Progression: Automatically advances the consumed media boundary on save success so rapid successive saves (e.g. 120s followed by 10s) produce only the newly captured delta while retaining necessary decoder preroll.
• Native Error Resilience & Windows Path Escaping: Correctly escapes Windows paths and quotes in native protocol error replies, preventing engine communication timeouts, and guarantees unique sequential filenames for rapid saves.
• Shell Explorer Selection & Settings Integration: Added native Windows SHOpenFolderAndSelectItems explorer selection support and exposed the new saveInPlace preference (default on) across frontend settings and host adapters.
